FalconX transferred 954 BTC, valued at approximately $61.4 million, to an unidentified wallet on Sunday. The move is notable because it comes within days of a separate on-chain event in which a wallet dormant since 2011 sent coins to an address with a documented history of routing bitcoin to FalconX deposit addresses.
The 2011 wallet received its coins on July 16 of that year, when bitcoin traded near $10. The address held 49.97 BTC untouched through every market cycle, exchange failure and regulatory wave for more than 14 years. On Aug. 6, at 20:14 UTC, the wallet combined four inputs from its dormant address with two smaller inputs from other addresses and sent exactly 50 BTC to a SegWit address—the newer bc1-format that makes transactions more compact and reduces fees.
Arkham Intelligence data show the SegWit destination address had been active for several years before the 2011 coins arrived. The platform had previously recorded two outbound transfers from that address to wallets labeled as FalconX deposits: one of 6.336 BTC and a second of 16.131 BTC. The address has also received funds from wallets Arkham labels as a Nexo hot wallet and Prime Trust custody, indicating it sits inside a web of institutional counterparties rather than being a personal cold-storage wallet.
As of Friday morning the 50 BTC that arrived from the 2011 wallet remained in the intermediate address. No on-chain evidence placed those specific coins at a FalconX deposit address or any exchange. The 954 BTC outflow from FalconX on Sunday is a separate transaction involving FalconX as the sending party, not the receiving one.
Galaxy Research, which flagged the 2011 wallet movement, said the address's coins were accumulated when bitcoin was worth a fraction of a cent relative to current prices. The 49.97 BTC position is now worth roughly $3.2 million. The transaction was confirmed in block 961331.
FalconX has drawn attention before for large dormant-wallet flows. In May, two bitcoin wallets that had been inactive for roughly a year transferred 1,650 BTC—worth about $127 million at the time—directly to the institutional brokerage. That move dwarfs the current 954 BTC outflow in size, though the direction is reversed: Sunday's transaction shows FalconX sending, not receiving.
The context for any large dormant-wallet movement right now includes a major hardware wallet security event. Coinkite, the maker of the Coldcard hardware wallet, disclosed on Tuesday a firmware flaw dating to 2021 that left private keys generated by affected devices exposed. The company said attackers swept as much as $114 million from vulnerable wallets across four waves of thefts since July 30. Coinkite urged users to move funds immediately.
There is no evidence connecting the 2011 wallet or the FalconX transactions to the Coldcard vulnerability. The 2011 wallet predates the Coldcard device by years. But the disclosure has pushed long-term holders to audit old storage arrangements, which on-chain analysts say is a credible reason for dormant coins to appear on-chain after years of silence—separate from any intent to sell.
On-chain transfers from institutional platforms like FalconX to unlabeled addresses are not inherently sales. Institutional desks routinely rebalance custody arrangements, move client assets to segregated accounts, or shift coins between prime brokerage infrastructure. Without a subsequent transfer to an exchange deposit address, the destination of the 954 BTC remains opaque.
Bitcoin traded at $64,345 at 21:00 UTC Sunday, up 2.1 percent over the prior 24 hours. The Crypto Fear and Greed Index sat at 31, in fear territory. Combined centralized exchange volumes fell 23.9 percent to $3.76 trillion in July, the lowest reading since November 2023, according to Galaxy Research data. Decentralized exchange spot market share reached a record 19.5 percent over the same period.
